THE nnrio'nhncnsn moist n comrenmor DAYTON} o no, A conroi nnon or V MARYLAND Application filed April 8;1 92 4, Serial-No. 704,932. Renewed A pril 15, 1929.

This invention relates generally .to im provements in cash registers and has-partlcular reference to improvementsm the 'printing mechanisms ofrsuch machines.

In the accompanying drawings the improvements are shown applied to a machine. of the same general type as is shown and described in U. Sipatent to Frederick L. Fuller, Number 1,742,701, .and U- S. Patent 1,799,687 granted April 7 1931, to Fred S.-,

Haas. The latter application shows aZ-machine provided with mechanism for printing and issuing checks or printing upon inserted sales slips combined with devices whereby the mechanism may be conditioned for either check printing or sales slip printing. As

will be more clearly apparent later on, how

ever, the improvements are capable of; being applied to or embodied in a number of other forms of cash registers'and accounting ma-H chines without. departing from the spirit of the invention.

An object of the present-invention to.

provide improved interlocking devices efiiective to insure correct operation of the 1mprovedmachine as a Whole regardless of the condition under which the printing mecha-v nism may be operating; and assoc ated con-.5

mechanism is changedto sales slip printing condition or when 1t 1s desired for somereason to be able to. operate certain parts ofthe mechanism without teitherprinting and issuing a check or printing upon a. sales slip.

Another object oft-he invention is to rovide interlocking devicesit prevent ad ustmentor operation of thecontrolling. devices during an operation of the machine. The mechanism devised forefi'ectingthese,

various results is; however, cap able of being used for other purposes,either as a whole or in part, and the statement of the objects is not intended as a limitation in this respect.

The feeding operation is performed by a pair of co operating rollers driven by the handle, one of which rollers is provided with inked type for printing on the face of the check.

For certain classes of transactions, such as chargevtransactions, it is desirable to have the machine so constructed as to print upon an itemized charge slip a total of the items,

* n? mend n ar f n ring. got a, record of the transaction, in, the,

recoriiretaining devices of the machine. The improved machine is provided with a. slotinto which sales slips may be inserted to receive impressions,

In the present embodiment the work of conditioningthe printer for different kinds of printing is performed by adjustment of manipulative devices comprising a lever which. operates through suitable connections mechanism to free the keysfor-operation, but

freeing-them will at thelsametime affect the interlooking mechanism to prevent a second operation of the check; feeding mechanism without an intervening operation of-thekey} board Adjustment ofthe mechanism in preparation for slip printing frees the keys for successive operations without intervening operations of the check feeding mechanism, In fact, the feeding mechanism becomes locked so that it; cannot be actuated. To print upon sales slips when the mechanism is in slip printing condition, all; that is necessary istoinsertthe slips to a position where they may receive impressions from thetype carriers andthen depress the keys representin the items. This causes theitem's to be pr n-ted upon the slips, after which the slips are simply withdrawn from the machine. The mechanism for controlling the condition. of the printing mechanism is so constructed-that it maybe adjustednot only to prevent; insertion of-a sales slip, but also at the same'time to prevent operation of the mechanism v usually operated'to print upon checks or sales slips. The reason for this is that it may attime's be desirable to operate the keys ofthe machine Without either issuing checks or printingupon sales slips. hen in this non-printing condition the interlocking mechanism before referred to is throw-n out=of -action so that there no interference with repeated or successive operations of the keyboard.

When the mechanism is operated under check printing conditions, av pair of impression hammers is operated to make the impression, one for printing the consecutive numbers and theother to print the date. identifying characters and amount of the item. When the mechanism is adjusted to the non-printing condition both of the imprcssion hammers are inoperative, while under slip printing conditions only the consecutiye number impression hammer fails to operate. Under the condition last mentioned, herefore, e consecutivenumben type carriers do not print upon the inserted slips. And: as-the consecutive numberingdevices are operated to add one directly by movement of the check feeding devices the munber cannot be changed: or increased, because, it Will be recalled, the feeding mechanism becomes locked when the printing mechanism is prepared" for slip printing.

The cont roll ingmechanism just referred to cooperates with devices rendered effectiye at the start of an operation of the mach ne whereby a difierentcondition cannot be set up until-the operation is completed.

'Dheo crating. keys work in slots 20 (Figs. 1 aud t in themachine casing and are pivotedon 'arod 21' extending across the ma chine. Resting. upon all of the keys is a key coupler2'2- pivoted a-s M23 in the side frames of: the machine. When the outer ends of the keys are depressed the key coupler is rockedon its pivotandengages withnotchcs 24in the rear portions ofthe keys. The construction and purposes of such key coupler mechanism are well known in the art and need iiot bedescribed in detail.

Connected to the key coupler is a double rack 25 (Figs. 1 andQ) the construction being such that as the key coupler rocked by the keys the rack 25 is, raised and lowered. The teeth of the double rack enga e a gear 26- (Fig-. 2) secured to the shaft 2t, first on one side andthen on the other in such a way thata complete movement of the key coupler 22 a.n(l double rack 25 will effect a complete rotatipn of the shaft 27. The sh aft 27 carries cams and other devices for operating various parts of-the mechanism. The mech anism for effecting rotations of the shaft has notbeen described'in detail because it old andso wellknown this construction being shown and described, for example, in the patentto Carney 786,346, April =1, 1905.

The illustrative machine is provided with four special) or transaction keys for Paid out, Charge, Received on account and No sale items, designated respectively by the numerals 54, and 56. (Fig. 2). The No sale key has certain functions such as operating drawer release mechanism. but it does not set a type carrier. There is a type carrier provided for printing the charactors designating the various special keys, but it normally heldin aposition to print he character representing Cash which cl .racter like ise serves in the present embodiment to designate No sale transactions. and is shifted to any of the three other positions by the corresponding one of the keys 53, 5 1 or 55. Each of these keys is provided with a stud 57 (Fig. 1) engaging a cam slot 59 forn -ed iira'cain plate 58 secured to a tube 60 surrounding a shaft 36. The slots in the plates are graduated so that each key will impart different degrees of movement to the tube 60. -The rearward portion of each. cam plate cut away as at 61 (F 1) so that the cam plates may be moved forwardly when a key is depressed without interference by the studs on the undepressed keys.

The tube .60 terminates, at its right hand end at substantially the central portion of the machine (Fig. 2) and has secured to it a yoke 62, thoright hand end of the yoke being secured to a similar tube 63 for setting up the type carrier in the new printing mech anism. Secured to theyoke 62 is an arm 64 (Fig. 1) connected to an extension of a segmental rack 65 meshing with a pinion rigidly connected to the type carrier 40 ofthe old recording mechanism, having on its periphery type for printing characters to represent the various classes of transactions. From the foregoing it is clear that the differential movements of the tube 60 by the associated keys will effect corresponding movements of the type carrier to its various printing positions.

The connections for transmitting movements from thetube 60 to the type carrier of the new printing mechanism comprise an arm 66 secured to the extreme right hand end of the tube and a link 67 (Fig. 1) the upper end of the linkibeing connected to a downward extension 671 of a segment 68, (Figs. 2 and 5), similar to segment ltSlIOWH in Fig. 6, loose on a shaft 101. The segment 68 meshes with a gear 69 secured to'a tube (not shown) loose on a shaft 50 integral with a type carrier 70 (Fig. 3) having on its periphery the type for printing various classes of transactions. 1 r a V The two keys shown in Fig. Q-designated 31 and 32 are th-e'keys for two clerks or two departments. For conyenience they will. be referred to as the A and B clerks keys. They are connected with and operate mechanism for controlling engagement of either the totalizer A. or the totalizer B, (Fig. 1) with operating segments of the differential mechanism. T he totalizer engaging mechanism isnot directly involved in the present invention, and is not shown ordescribed in this application. A showing and descriptionof one form thereof may be found,

The A key 31,.in addition to its totalizer selecting or engaging function, operates an indicator and does certain other work, but is not connected to devices :for setting a type carrier. Patent 1,742,701 has, however, a type carrier for printing either the letter A or the letter B upon the record strip and, in addition thereto, a sin'iilartype carrier is inhowever, in the Fuller applicationabove mentioned.

The machine shown in the Fuller cluded in the improved mechanism to print upon the check or inserted slip. The position of these two type carriers is controlled by the B key 32.

naled in suitable cars 19 (Fig. fastened to the base of the machine. It is apparent that when the B key 32 is depressed it will act through the connections described to rock the shaft 36 clockwise (Fig. 1) and that when the key 32 returns to its undepressed position the shaft 36 will be restored to its starting point. a

Secured to the shaft 36 is another arm 37 (Fig. 2) similar to arm 64 (Fig. 1) of the transaction banln'bifurcated at its rear end to engage a stud 38 carried by a downward extension of the A and B type carrier segment 39 of the recording.mechanism just as shown in the Fuller application. The movement of the shaft 36 will adjust the A and B type carrier from its normal position to carry the A type away from and bring the B type to the printingline whenever the B key is depressed. v

The connections for transmitting movements of shaft 36: to thenew type carrier '41 (Fig. 3) comprise an arm 42 (Figs. 2 and secured to the shaft 36 and connected by a link 4-3, (Figs. 5 and 6), to an extension of a segment 44 loose on a shaft 101. The teeth ofythe segment 44- are in mesh with a pinion 46 secured to a tube loose on a shaft 50 6) journaled in the new mechanism support-, ing frames, and integral with the type carrier 411 provided with the A and B type.

To the ri ht of the transaction "roan of b A keys in a series of seven keys 80, for entering items running from $1.00 t0'$7.00 only two of which keys are shown (Fig. 2). Each key 80 is provided with an upwardly extendin arm 81 best shown in Fig. 1, carrying a stud 83 engaging a slot in one of a set of plates 84 rigidly mounted in a frame 85 mounted loose on the shaft45. The slots in the plates 8% are graduated so that each of the keys will'impart a different degree of movement to the frame 85 and consequently to parts attached thereto. Rigidly secured to the frame 85 is an arn'r 86 connected by to print an amount corresponding to th nine of the key depressed.

l\flouuted 1n extensions of the rock lia 1c 11 is a rod 95 (Fig. 2) extending beyo d tl mine to a segment 96 loose on the sh This segment is for setting the dollar carrier in the old recording mechz'inisn'i and actuating the dollars wheel of the totalizcrs. It. is clear that a differential moyen'ient of the rock frame under control of its a sociated keys will effect corresponding moi"?- meut of the segment- 96 and of the dollar type wheel.

To the right (Fig. 2) of the dollar differenial frame is a differential frame 98 operated by the 10 to keys to impart different degrees of movement to the associated mechanism. It will be seen that the shaft is journaled at its left end in the frame of the machine and terminates at its right end at the point marked 99. This point of termination is within a hub 100 secured to the shaft 10]. previously mentioned, which shaft is rotatably supported by the right hand machine frame and by a bracket 102 on frame [103 (see also Fig. and which in the illustrative n'lachine supports the totalizers and recor l strip printing mechanism. The frame 98 is, at its left side, loose upon the shaft 415, and at its right integral with the huh 100. Secured to the shaft 101 is a segment 10%- substantially similar to the segment 92 of Fi s. 2 and G and meshing with a gear 105 (F 3) connected by a tube (not shown) 2': to a type carrier 106 for printing characters representing 109 to 90 amounts in th new red ng mechanism. R gid with the frame 98 is a segment 10'? (FigzQ) ope 'ating the dimes type ca rier in the old recording 1n chanism and the dimes registering wheels of the totahzers.

The penny keys operate upon -am plates (Fig. 2) fastened. in a. differential frame lit), in the same manner as hereiuhcfore described in connection with other groups of s. The are iine of the penny l-tcys and t. eir connections with the (I ential frame it) are such that by selective operation of them the frame may be moved to nine di. ent gositions. Secured in extensions frame 110 is a rod lll engaging a 1 H2 loose upon the shaft iz). This sign. 1 operates the penny type carr'cr in the recording mechanism and the corre-ipomlin wheels in the totalizers. Secured to the ight hand side of the differential penny frame 110 is a segment 113, Figs. 1, 2 and 3. enganing a gear 114:, connected by a tube (not shown) to a type carrier 116 for printing the characters representing 1 5 to 9;".

In axial alignment with the type carriers ill, 70. 94. 106 and 116 are type carriers 11$, and 120 (Fig. 3) for designating}; dates. feshing with the teeth of a pear rigid with he type :arrier 118 is a 121 secured to a. shaft 122. At its right hand end the shaft;- is provided with a knurled knob 1.523 by means of which the type arrier 118 may be adjusted to the different positions. The rintiug; face of the type carrier years type for printing characters representinrj the months. The type carriers lit) and 120 are 'r-ovidcd with similar n'wshing with gears 124i and 1525 rigid with tuhes 126 and provided with setting: knobs 128 and 1.2!) b means of which the type :arriers 11.9 and and the mechanism for operatin are of the usual deep notch transfe type. ii hail 1235, Figs. 3 and t loose upon the shaft supports the usual operating; and carrying pawl 136. One side of the bail is connected by a link 13?, (Fig. at) to an arm 138 secured to a shaft 139 To the op- )osite end of the shaft is Secured an arm 14:0 provided with a stud 14-00 (Fig. engaging a bifurcation fo med in the vertical arm of a hell crank M01. The bell crank A101 is loosely mounted upon the sh Lil and its horizontal arm H2 has a cam slot 14.3 engaging a stud 144.011 the side of the feeding; lever H6. This lever, which has an operating handle 147, is moved each time that a check issued and conse piently acts through the stud l tl, cam slot 143 and other connections described to escalate the hail a sufficient distance for h e pawl 136 to add one on the consecutive numhering type carriers. Sprhin 'uessed pawls 151 retain the munhcn inp; ty ie 'arriers in their '\'arious positions.

The ink for printing from the consecutive numbering type carincrs and the other type carriers in anal aligrmnent th rewith is supplied by an inked rihhon fla l. Fi passing); helow the type carriers arouml supporting rollers 15?, and a roller 14a of felt or other material capable of carrying a n ink supply for the ribbon. T he rolle 1516 is roissues tatable on a rod 157and pivoted on this rod at one end of the roller 156 is an arm 158 carrying another roller 159. Inte al with the arm 158 is an arm 160 connected y sprin 161 to the printer frame (Fig.3). The ri bon passes back of the roller 159 so that the spring 161 can serve to maintain a certain amountof tension upontheribbon. y

The ribbon is givena step ofmovementat each operation of the 5 machine, This. not only prevents successive 'im ressions through the same portion of the ri bon, but it also serves to bring the different portions of the ribbon into contact with the roller 156 and thereby permits the roller to moisten. or apply ink to the ribbon. The mechanism for driving the ribbon comprises a ratchet disk 163, Fig. 4, rigid with theroller 156 and a pawl 164 carried by an arm 165 loose on the rod 157. The arm 165 carries a stud engaging a bifurcation in one arm of a bell crank 166 pivoted upon shaft 141.' The horizontal arm of thebell crank is similarly connected to a second bell crank 167 (Figs. 4 and 6) loosely mounted on a transverse shaft 186, the vertical arm of the bell crank 167 carrying a roller 169 to engage an eccentric cam 170 secured to the shaft27. The shaft 27, it will be recalled, m'akesa complete rotation at each operation of the machine, and the mechanism just described is so proportioned and conneeted that ateach rotation the pawl 164 will be operated to impart a step ofmov'ement to the rachet. disk163 and the roller 156.

The impressions are taken from the consec utive number, date and item carriers by two percussion hammers, one for theconsecutive number, and the other for the rest of the type carriers. The consecutivenumber hammer 17 5, Figs. 3 and 4, has a'hub 176 loose on a rod 177. At its forward end it carries an adjustable impression block 178 of rubber or other suitable material of suflicient length to take an impression from all three of the consecutive number type carriers. The impression hammer 181 (Fig. 3) for printing from the rest of the type carriers issubstantially the same as the consecutive type hammer, and has a hub 18 2'loose on the rod 177. At its forward end the hammer 181carries an impression block which is not shown in the drawings, but is the same as the impression block 178previously described, except that it islongenough to print from all of the date and item printmg type carriers.

Printing movement is imparted to the impression hammers by an arm 184'pivoted on the rod 177 bet-ween the impression hammer hubs 176 and182, The forward edge of the arm 184 has a shoulder185 engaging the rod 186. Near itslower endthe arm 184 carries a stud 187 in the plane of rotation of a cam 188 fastenedto the rotation shaft 27. During the rotation of the shaft the cam will act against the stud 187 to "swing the arm tending at right angles to its length and en- 184 against the tension of a spring 189 until the cam passes out of engagement with the stud whereuponthe spring 189 will snap the arm 184 forward until it is arrested by the rod 186. The arm 184 has a portion 192 ex- The mechanism previously mentioned whereby the impression hammer 175 ma be prevented from printing or by whic junder certain conditions both hammers may be disabled, performs its function by move ment of the hammer or hammers toward the type carriers far enough to carry the studs 1.93 out of engagement with the normally coacting. portion 192 on the hammer operating arm 184 and holds them in that position.

With this in view the consecutive number 5 hammer head 175' is provided with a stud 195, Fig. 4, and the other; hammer 181 with a similar stud 196 (Fig. 8). Attached to the shaft 141 is a pair of arms 197 and 198 (Figs.

5 and 8). The arm 197 has anextension'199 (Fig. 4) having a cam surface 200 to engage thejstud while the arm 198 has a similar extension 201and cam surface to engage the stud 196 secured to the hammer 181.

V Secured to the shaft 141 is a controlling lever 205 which, as shown in Fig. 6 is adjustable to three positions, marked respectively Check, Lock and Slip. The construction and relation of the parts is such that when the controlling lever 205 is at the check posilion neither the stud 195 nor the stud 196 willbe engaged by the cam surfaces on the arms 199 and 201 and the hammer operat ing arm '184-will, when'it snapsforward, impart-printing movement to both of the hammers. When the controlling lever 205 is moved to the lock osition the cam surface on the arm 201 will brought into engage ment with the stud 196 on the date and amount hammer 181 and the cam surface 200 will be brought into engagement with the stud 195 on the consecutive number hammer 1 75. The cam surfaces are so graduated that they will act against the associated studs to move the hammerstowards the type car- 'ri'ers far enough to hold the studs 193 on the hammers out of engagement with the .operating portion 192 of the hammer operating arm 184. As a result neither of the hammers will be operated to make an impression.

- hen the lever 205 is moved to the slip position the cam surface on the arm 201, (Fig; 8) which surface is comparatively short, will be carried past its associated stud, while the cam surface 200 of the arm 199 will, because of its greater length, remain in engagement with the stud 195 and hold the and 6) of paper or other suitable material,

loosely supported by a stud 207. The strip passes from the roll 206 between plates 208 and 209, connected together and slidably supported at the rear end by a plate 210 attached to the machine easing. At their for ward ends the plates are supported by a rod 211 engaging slots at the upper ends of the arms 197 and 198 previously mentioned. Between the two plates, may, if desired, be placed a leaf spring 1212 which coa cts with the upper plate 209 to provide a tension device for preventing accidental movement of the paper relative to the plates. As previ ously pointed out, the arms 197 and 198 are moved by operation of the control lever 205 and owing to the engagement of the arms with the rod 211 any movement of the control lever and arms will be transmitted to the check paper table or chute and this movement, owing to the tension spring 1212 will serve to shift the check strip slightly toward the front of the machine.

In most places of business, checks, or, as they are sometimes called, receipts, will be required for a majority of transactions entered in the machine. When a check has been fully ejected by operation of the mechanism it is torn off from the strip, the rear edge 213 of the plate 209 serving satisfactorily as a tearing guide. The next check to be issued will, therefore, have one end adjacent the tearing edge 213 and will rest between a roller 214 and a roller 215, the latter having on its periphery an electrotype for printing any desired matter. In the present machine the electro is designed to print the name and address of the proprietor. The rollers 214 and 215 are geared together and are driven by movement of the check feeding lever 146. The feeding lever carries a segmental rack 216 which, during movement of the lever will engage a gear 212 (Fig. 4) loosely mounted ona stud 228 which is carried by an arm 218. The arm 218 is loose upon the shaft 219 which supports the roller 214. Secured to the gear 212 is a larger gear 217 meshing with the gear attached to the roller 214. Due to the fact that the preponderance of weight is on the forward end of the arm 218 the teeth of the gear 212 will fall in mesh with the teeth 216 of the segmental rack. WVhen the handle 147 is swung rearward the rollers 214 and 215 will be given a complete rotation and during the return movement the teeth of the gear 212 will ratchet over the teeth 216, by reason of a locking pawl 225 holding the gear against reverse movement. The locking pawl 225 is loose upon a. stud 234 and is held in engagement with the inter-dental space of the ear by a spring 226. The arm 21.8 is furt ier provided with a rearward extension 230 which, (as the gear 212 ratchets over the teeth 216) is depressed to cooperate with an arm 229 integral with the pawl 225 and force the pawl into positive engagement with the inter-dental spaces of the gear.

A full stroke mechanism is provided to compel a complete movement of the lever 146 and its handle 147 in both directions. This full stroke mechanism comprises a plate 233 Figs. 4 and 6, attached to the feeding lever or handle and concentric with the teeth 216. Pivotally supported on a stud 234 is a pawl 235. l/Vhen' the segment 233 is moved toward the rear of the machine to feed out a check the pawl 235 will be swung slightly on its pivot and then act with the notches in the segment to prevent reverse movement of the handle. At the end of the check feeding stroke of the handle the pawl 235 will drop in front of the rack 233 and then during the forward movement of the handle will be swung the other way and co-operate with the rack to prevent reverse movement of the handle until after the movement back to its normal starting point has been completed.

In machines of this type it is sometimes desirable that interlocks be provided for con trolling the sequence of operations of the machine. The machine in the drawings has an interlocking mechanism so constructed that after a key or keys have been operated to print upon a check the keys will be locked against depression for a second operation until after the check handle has been actuated to feed a check. Locking mechanism is further provided for preventing a second operation of the check feeding handle but a subsequent operation of the keys will disable the locking mechanism to release the check feeding mechanism.

This mechanism is best shown in Fig. 4. The parts are all shown in the positions they occupyafter an operation of the keys with the machine in check printing condition. At this stage the shaft 27 is held against rotation by a shoulder 242, on a disk 243 attached to the shaft, engaging :1 lug 244 on an element 245 pivoted at 246 to the side of a bellerank 247 journaled on the shaft 186. A spring 248 tends at all times to rock the elements 245 in a clockwise direction on its supporting pivot while a spring 240 connected to the upper arm 256 of the bellcrank 247 insures contact' between the disk 243 and element 245 at all times when the lever 147 is not displaced from normal position. Disengagement of the lug 244 from the shoulder 242 is effected by rocking the bell crank 247 on its pivot 186 against "the tension of spring 240 thereb swinging the lower end of the bellcrank 247 rearward and the element 245 far enough to release the disks 243 and shaft 27.

This niovement ofthe bell crank 247 is im-' parted during the rearward stroke of the feeding handle 147 The means for effecting thiscomprises the stud 144 co-operatingwith cam slot 249 formed in a plate 250 loosely pivoted upon the shaft 186. The plate 250 is further provided with a downward extension or tail 251 abutting against a stud 252 secured to the bell crank 247. Spring 248 is provided with sufficient tension to tend to rock the element 245 clockwise as well as to pull plate 250 downwardly, but as clearly shown in Fig. 4 the downward movement of plate 250 is limited by engagement of tail 25?. with the stud 252 carried by bell crank 247.

When the feeding lever is moved rearwardly the stud 144 moving in a path concentric with the shaft 101 engages the lower edge of the cam slot 249 depressing the forward-end of the plate 250 downwardly, and by virtue of engagement between the tail 251 and stud 252 rocking bell crank 247 rearwardly, there by disengaging the locking lug 244 from the shoulder 242. Then the lug and shoulder become disengaged the spring 248 will swing the element 245 clock wise and as the check lever is returned to its normal position the locking lug 244 will rest upon the periphery of the disk 243 thus liberating the rotation shaft 27 and operating keys for operation.

After the feeding handle147 hasbeen given a full rearward and then forward movement to feed a check, and the shaft 27 freed for rotation, the keys may be depressed to register the neXt item. During this registration the shaft 27 w1ll be g ven its usual complete rotation. Near the end of its rota tion theloeking lug 244 will engage the cam portion 253 and the spring 248 will draw the lug towards the center of the rotation shaft, and near the end of its rotation the shoulder 242 will engage the locking lug'244 and swing the element 245 to the position shown in Fig. 4. v

After a check has been issued it is, of course desirable to prevent a second operation of the check feeding mechanism until the keys have again beenIoperated and the machine thereby placed in check printing condition. The cam plate 250 is further provided with a locking slot 254 which engages-the stud 144 to lock the check handle against a second operation when a: check has been issued and the check handle returned to normal position. WVhen the check handle is moved rearwardly he lug 244 will rest upon the periphery of the cam plate 250 downwardly. As the check handle is returned to its normal position the cam-plate will snap down at the time the stud 144 is in line with the locking slot 254 thereby locking the check feeding handle. When the keys have again been operated the spring 240 connected to the bell crank will force stud 252 forwardly, carrying with it the tail 251 of plate 250, whereupon the parts will again assume the positions. shown inFig. 4, the stud 144 being disengaged from the slot 254 and the check feeding handle freed for operation.

In addition to its other functions; the bell crank lever 247 controls a lock for preventing the shifting ofv the printing control lever 205 to either its lock or slip positions until after the last check printed upon has been fed out of the machine. The upper arm 256 of the bell crank lever 247 has a shoulder 257 which co-operates with rod 258 journalled between the extensions 199 and 201 (Fig. 8) on the arms 197 and 198. When the machine is in the condition shown in Fig. 4 the control lever 250 cannot be moved forwardly to its lock or slip positions due to the co-operation of the rod 258 with the shoulder 257. When a check has been issued and the shaft 27 freed for rotation in the manner hereinbefore described, so that the element 245 rests upon the periphery of the disk 243, the arm 256 of the bell crang lever will have been rocked downwardly thereby withdrawing the shoulder 257 from the rod 258. The control lever 205 may then be moved to either lock or slip printing position. v

During rush hours it may be desirable to be able to use the registering keys without being compelled to operate the check feeding handle 147. It is necessary, therefore, to be able to disengage the locking lug 244 from the shoulder 242 and hold it disengaged when printing is discontinued or when the machine is changed from check printing to sales slip printing condition. The mechanism for doing this comprises a forwardly extending finger 259 on the bellcrank arm 256 provided with a cam edge 260. As has been stated previously, when a check .has been issued the shoulder 257 will be withdrawn from looking co-operation with the rod 258. If the parts are in this position and the control lever 205 moved forwardly to its lock position, the rod 258 will be moved forwardly and, thru the cooperation of the rod 258 and cam edge 260 the bell crank 274, will be held rearwardly soas to prevent the engagement of the lug 244 with the shoulder 242 upon subsequent operations of the machine. Movement of the control lever 205 still further to the slip printing position will result in maintaining the rod 258 in engagement with cam surface 260 so that rocking of the bell crank 2i? will still be prevented or a slight added rearward movement may be given to the bell crank 2&7, and thereby simply carry the locking lug 24rd still further away from the path of the shoulder 242. It is clear, therefore, that with the control lever 205 set at either its lock or slip position, the keys and the rotation shaft 27 driven thereby a re all free for operation without its being necessary to manipulate the checl: feeding handle 1&7.

hen the control lever is in its lock or slip printing position it is desirable to prevent irregular operations of the machine by locking the check feeding handle 147 against operation. It will be clear, of course, that when the control lever 205 is moved to either its lock or slip position, the bell crank 247 must previously have been moved rearwardly by the last operation of the check handle and held in this position by the means just described and the spring 241-8 will. then have rocked plate 250 downwardly and engaged the stud 14d with the locking slot 25-1, thus continuously preventing any movement of the feeding handle 1.47 so long as the control lever is moved to either its lock or slip position.

The sales slips are inserted into a slot 27%: far enough to bring between the type ca tiers and impression han'nner the poi-ion of the slip upon which the impression should fall. The Haas application previously mentioned discloses mechanism whereoy insertion of a sales slip will be prevented when the printer controlling lever 20:: is either at its check or lock posi ion, and since this feature is not involved in the present invention, it will not be described herein.

As already stated when the control lever 205 is moved from the check position to the slip position the check paper table will be moved foiwu'irdly a corresponding amount and by reason of the fact that the tension s1 ring 1212 et) urges the check strip against the plate 209 movement of the check paper table will serve to draw the check paper away from its position between the rollers 214 and 215. As will be seen in Fig. 4, the rollers are cut away or flattened for a portion of their peripheries so that at their normal positions this movement of the paper is permitted. It will be understood that when the control lever 205 is in the check position. the check paper will be printed upon on a line a certain distance away from the severing point or tearing edge 31.3. but when the control lever is moved to the slip position the. shifting movement of the check strip as explained above, will cl'iange the printinn' line to a point nearer thescvercd edge of the strip. It should be understood however that the shifting; movement of the check paper is not sufncient to bring the check strip out of (Jo-operative relationship with the platen and item type carriers. 1f the operator should adjust the control lever to the slip position and forget to insert a slip in the slot 274., it will be obvious that the pri; 'eg impression will be etlected upon the check strip on a line removed from the normal printing line. If a subsequent operation should now be one requiring printing upon and issuing a check, the control lever would he returned to the check position, thereby reversely shifting the check paper so that when the keys of the machine are subsequently operated a second impression will be made upon the check strip within the limits of one check. The last impression, which is the proper one to be considered will be the lower one on the severed checl; and its position will indicate which of the two impressions is the proper one.

However, in order to prevent contusion by reason of the fact that two amounts will be printed upon the same check the electro roller may be so formed that when the check strip is issued from the machine special type carried by this electro will overprint and delete the improper impression thus permitting only one item to be readable, that being tho one corresponding to the amount entered when the control. lever "as in the check position.

The mechanism for accompiishing the above forms no if art of the present invention. and is, therefore, not shown or described in detail and for further details reference. may be had to the application of Frederick L. Fuller, Ser. No. 594,296, filed October 12), 1922. y
